Memory in Eclipse

I'm getting the java.lang.OutOfMemoryError exception in Eclipse. I know that Eclipse by default uses heap size of 256M. I'm trying to increase it but nothing happens.

For example: eclipse -vmargs -Xmx16g -XX:PermSize=2g -XX:MaxPermSize=2g

I also tried different settings, using only the -Xmx option, using different cases of开发者_如何学C g, G, m, M, different memory sizes, but nothing helps. Tried also to specify the values in the eclipse.ini file. Does not matter which params I specify, the heap exception is thrown at the same time, so I assume there's something I'm doing wrong that Eclipse ignores the -Xmx parameter. I'm using a 32GB RAM machine and trying to execute something very simple such as:

double[][] a = new double[15000][15000];

It only works when I reduce the array size to something around 10000 on 10000.

I'm working on Linux and using the top command I can see how much memory the Java process is consuming; it's less than 2%.

Thanks!

Okay, I found a solution after reading Why does heap space run out only when running JUnit tests?

When I specify the -Xmx inside eclipse by going to run->configuration->vm arguments and set the -Xmx there, everything works fine :)
